Computer engineer Otaku (the Japanese term for "geek") is an average young man, dressed in unstylish clothes and dorky glasses. But as luck would have it, he encounters a pretty young woman on a commuter train and saves her from a lecherous molester, falling in love with her at first sight. A few days later he receives a thank-you message from the woman along with a set of Hermes teacups . Having never had a girlfriend or received a gift from a girl in his life , Otaku seeks out his pals on Internet Bulletin Board (BBS) website for advice using his codename Train Man (Denshi Otoko): "How should I ask her out?" Deeply interested in Train Man's first love, his BBS pals eagerly supply him with advice. Encouraged by their support, Train Man undergoes a total makeover for his first-ever date with "Hermess." Little does he know that he is about to ignite an Internet phenomenon . (Source: AsianMedia Wiki)
